System-Wide Problems
Symptom
Steps to Take
System fails to come up.
1.
Check the Power LED on the NI-2, the Status LEDs on the line cards, and the Input OK LED
on each PEM. If all LEDs are off, or if the red Out Fail LED on either PEM is on,
troubleshoot the PEMs. See the
“Alarms” section on page 5-17
.
2.
If any green LEDs are on, the system has power. Check the STATUS LED on the NI-2 card.
If the STATUS LED is off, refer to the
“NI-2 Card Problems” section on page 5-8
.
3.
If the Cisco 6260 is set to boot from a remote device over the network, make sure the remote
device is up, that its network connection is solid, and that it contains the boot file. (The
Cisco 6260 tries to boot over the network for a configured period, usually 5 to 15 minutes.
If it is unable to boot over the network, it will eventually boot from bootflash.)
4.
Try to establish a console connection to the Cisco 6260. If you cannot connect, see the
steps for the symptom
You cannot establish a console or Telnet connection to the system.,
page 5-4
.
5.
If you achieve a console connection
–
Examine the command prompt. If the prompt says
rommon 1>
, the problem could be in
flash memory, in bootflash, in an incorrectly set boot configuration register, or in an
incorrect file name in a
boot system
command in the startup-config file. Refer to the
Configuration Guide for Cisco DSLAMs with NI-2
for information on setting and
interpreting configuration registers, configuring flash memory, and editing the
startup-config file.
To select an image to boot the system from flash, enter
dir flash:
. In the resulting
display, find the name of the software image. Then enter
boot flash:
imagename
,
replacing
imagename
with the name of the software image. The system boots
from flash.
–
If you see a normal Cisco IOS prompt, which usually contains the name of the system
(default is
c6260
)
, enter
show oir status
. If the results indicate that the card is loading
software, wait a few minutes for the port to come back up.
